Abstract: A pedal pad includes a plate part having a plate shape. When a driver performs a depression operation on a plate part from one side in a plate thickness direction, the pedal pad rotates about an axis perpendicular to an extending direction of the plate part. A shaft member is provided at a position away and downward in a vehicle from the plate part. A housing rotatably supports the shaft member. A connecting portion connects the pedal pad and the shaft member. Such a pedal device is an organ-type pedal device in which a pedal lower end is positioned below in the vehicle than a pedal upper end when the plate part is not subject to the depression operation by the driver in the non-depressed state. The pedal device is provided with a gap between the housing and the pedal lower end.

Abstract: A pedal pad in an organ-type pedal device swings about a predetermined axis when stepped on by a driver's foot. A sensor unit outputs a signal corresponding to a swing angle of the pedal pad. A reaction force generation mechanism generates a reaction force against a driver's stepping force applied to the pedal pad. A first housing holds or covers at least one of a rotation shaft provided at the axis of the swinging of the pedal pad, the sensor unit, and the reaction force generation mechanism. A second housing is made of a rigid portion having a Young's modulus greater than that of the first housing or has the rigid portion at least in part. The second housing is configured to support a portion of the reaction force generation mechanism on one side opposite to the pedal pad by the rigid portion.

Abstract: An electromagnetic actuator, which is arranged at a position opposing to a hydraulic control valve, has a movable-core chamber for movably accommodating a movable core and an air breathing passage for communicating the movable-core chamber to the atmosphere. An inside opening of the air breathing passage is formed in an inner wall of the movable-core chamber, while an outside opening of the air breathing passage is formed in an outer wall of the actuator, which is in contact with the atmosphere. The outside opening is formed at such a position out of an oil-splashing area, to which oil discharged from an oil-discharge port of the hydraulic control valve is directly splashed. According to the above structure, it is possible to prevent the oil discharged from the oil-discharge port from rushing into the movable-core chamber through the air breathing passage.
Abstract translation: 设置在与液压控制阀相对的位置的电磁致动器具有用于可移动地容纳可动芯的可动芯室和用于将可动芯室连通到大气的空气呼吸通道。 空气呼吸通道的内部开口形成在可动芯室的内壁中，而呼吸通道的外部开口形成在与大气接触的致动器的外壁中。 外侧开口形成在从油压控制阀的排油口排出的油直接喷溅的喷油区域的这样的位置。 根据上述结构，可以防止排油口排出的油通过空气呼吸通道冲入可动芯室。

Abstract: A pedal device includes a pedal and a reaction force generation mechanism. The reaction force generation mechanism includes a resilient device and a first holder. The first holder contacts the resilient device from one side, which is a side where the pedal is placed. The first holder has a primary disengagement stopper. The reaction force generation mechanism includes a second holder that contacts the resilient device from another side, which is opposite to the one side. The second holder has a secondary disengagement stopper. In a non-depressed state of the pedal, the pedal limits movement of the first holder toward the one side. When the pedal no longer limits and thus releases the movement of the first holder, the secondary disengagement stopper limits the movement of the first holder relative to the second holder beyond a predetermined limit toward the one side.

Abstract: At a pedal device, a force applied from a pedal at a time of rotating the pedal moves a first guide portion of a first holder to slide relative to a second guide portion of a second holder in a vehicle front-rear direction, resulting in deformation of a first resilient member. Furthermore, the force applied from the pedal at the time of rotating the pedal moves the second guide portion to slide relative to a third guide portion of a guide member in the vehicle front-rear direction, resulting in deformation of a second resilient member.

Abstract: A pedal device for a vehicle includes a pedal unit, a rubber member and a restricting member. The pedal unit is displaced by receiving a pedal operation from a driver of the vehicle. The rubber member is pressed by the pedal unit displaced in response to the pedal operation and generates a reaction force against a displacement of the pedal unit. The restricting member is configured to restrict the displacement of the pedal unit separately from the rubber member, when the rubber member generates the reaction force.

Abstract: A pedal device includes a shaft, a pedal, a housing, a reaction force generating mechanism, and a connecting rod. The connecting rod includes an arm portion and a push portion. The arm portion is connected to a back surface of the pedal. The push portion is connected to the arm portion. The push portion is configured to transmit force from the pedal to the reaction force generating mechanism by contacting the reaction force generating mechanism when the pedal is stepped on by an operator. Further, the connecting rod is connected to the back surface of the pedal, to rotate with the pedal about the axis of the shaft when the operator steps on the pedal, while an angle defined between the back surface of the pedal and an axis of the connecting rod is maintained.

Abstract: A pedal pad in an organ-type pedal device swings about a predetermined axis when stepped on by a driver's foot. A sensor unit outputs a signal corresponding to a swing angle of the pedal pad. A reaction force generation mechanism has an elastic member that generates a reaction force against a driver's pedaling force applied to the pedal pad. A first housing covers the reaction force generation mechanism, and an opening at least on one side. A second housing is provided on one side of the first housing in a swing direction of the pedal pad. Further, the first housing has a largest opening on a second housing side, which is closed by the second housing and into which the elastic member of the reaction force generation mechanism in a non-bending state is insertable.
